NTI UNIMUX SINGLE-USER HIGH DENSITY VGA USB KVM SWITCH
CASCADING
The UNIMUX USB Matrix switch can be expanded to access up to 1024 CPUs by cascading multiple units together. As many
switches as there are CPU ports may be connected to a UNIMUX USB Matrix switch. (See Figure 41) All downstream switches
are referred to as "slaves" in a cascaded system. The only additional hardware required to cascade switches is a set of device
and monitor cables for each "SLAVE UNIT" (see MATERIALS on page 2).
users using OSD commands with Command Mode.
Limitations
The front panel keypad is only used to operate standalone switches. To control a cascaded network of switches, only the OSD
commands within Command Mode will be recognized.
Users connected to accessible ports on downstream slaves (i.e. ports not connected to the master) will not be able to control
switches or CPUs connected upstream.
enabled. (See Figure 41)
Slaves in a cascaded system must be either all single-user switches or all multi-user switches, but not a combination of both.
Cable Connections
The same cable used to connect a CPU to the UNIMUX is used to connect two UNIMUX-USBV-xHD switches together-
HDUSBVEXT-xx-MM.
No other cables will be necessary.
1.
Connect the USB-A-male end of the HDUSBVEXT-xx-MM to the USER port on the slave.
2.
Connect the 15HD male at the same end of the HDUSBVEXT-xx-MM cable to the MONITOR port on the slave.
3.
Connect the yellow 15HD male end of the HDUSBVEXT-xx-MM to the CPU 1 port on the master.
Repeat this procedure for each USER and MONITOR port on each slave that is desired to be controlled through the master.
The same procedure can be used to connect multi-user switches (UNIMUX-nXm-UHDU) as slaves (see Figure 42).
